I like 'crankbusters'.
Anyway, so you've grossly overgeneralized again. I assume you count me
an anti-crank. But, contrary to your claim, I am not inclined to
captiously dspute cranks when they happen to be correct.
It's not hard for me. And I don't see it as an example of someone
merely captiously disputing a correct claim happened to have been made

I believe that you also need to assume that lim(x->a) g'(x)/h'(x)
exists; otherwise, the result may not hold.
I don't have a ready example for a 0/0 indeterminate, but an example
for an oo/oo indeterminate take lim(x->0) (x + sin(x))/(2x+sin(x)).
This limit equals 1/2 (divide numerator and denominator by 2), but if

I know that is exactly right. Einstein was indeed a nitwit, a

Einstein was no physicist but a nitwit, a plagiarist, and a liar.

It looks like you should use l'Hopital's rule twice.
Manipulate the two addends, -1/x and the other,
so that they have a common divisor, x*(1-exp(-x)).
Differentiate the divisor and (the sum of) the numerators
until you do NOT get 0/0 when you evaluate at x=0.
By l'Hopital's rule, IF g(a) = h(a) =0, then

I'm having a hard time figuring out what the function *is*.
I assume it is:
(-1/x) + [ (e^(-x))/(1-e^(-x))].
If that is the case, then simplifying the second fraction we get
[ (1/e^x) / (1 - (1/e^x)) ] = [(1/e^x)/((e^x-1)/e^x)] = 1/(e^x-1)

Thanks for that insightful and well written posting.
The question which remains is whether "physical manifestations of
arithmetic logic" can constitute a valid observation to a physicist.
My claim is that Descartes could not possibly produce a "thought"
which was reproducible, falsifiable, quantitative, qualitative, etc.

Using Taylor expansions at order 2 I get -1/2. Maybe you simply added

I'm trying to evaluate the limit of:
F(x) = -1/x + e^(-x) /(1- e^(-x)) as x-->0
The correct answer is -1/2. I cannot get the correct answer. No
matter what I do, I get it equal to -1.
Thanks for your help.

Re: completion

I think so.
If you localize at the prime ideal P, you get a local Noetherian
domain with maximal ideal (the image of) P. The regular sequence of
elements (x_1,...x_n) that generates P in R will also generate the
localization of P, and will be regular, since the quotient of the
localization R_P/(x_1,..,x_i) is the localization of R/(x_1,...,x_i),
